What are the benefits of custom-built vs. off-the-shelf payment systems?

Custom-built payment systems give you the flexibility to shape the platform around your exact business needs. Unlike off-the-shelf solutions that can be limited or hard to adapt, a custom approach means you get the features, integrations, and user experience you actually need, without unnecessary extras.

What Our Clients Say

Our biggest hurdle was finding a partner that understood the complexities of healthcare-focused development such as HIPAA compliance, patient-facing applications, and physician-facing dashboards. Velvetech worked as an extension of our team and helped us build a HIPAA-compliant physician platform and a new version of our mobile medical device app.

Velvetech recently assisted Healix with the software development and release of our online ordering system. The Velvetech team was focused and professional, consistently ensuring on time deliverables, which is crucial in our healthcare business. Velvetech provides professional service and an excellent customer experience. We gladly recommend their services.

My Company has partnered with Velvetech on 30+ projects since 2001 and they have consistently exceeded our expectations in design, delivery, and product performance. They bring extensive IT and programming knowledge to our discussions and the team consistently maintains the highest level of customer service and focus.

We didn’t have the resources in-house to accelerate our opportunities, and we would still not be to market if we hadn’t gone to a very capable outside contractor to help to accelerate our process. Velvetech were very articulate, polite and professional. We’re very pleased with our working relationship with Velvetech and hope they can be part of our operation into the foreseeable future.

How much does it cost to build a secure payment platform?

A basic MVP may start around $50,000–$100,000, while a full-featured, enterprise-grade solution with multi-currency support, fraud protection, and companion apps might exceed $250,000.
